Solve the following system of equations. Give your answer as an ordered 5x + 2y = 16 3x-2y = 0 Solve the following system of equations. Give your answer as an 4x +.3 y = 7 x - 2y = -1

Solution

QUESTION 1

5x + 2y = 16                                        x =2

3x – 2y = 0      +                                  3x – 2y = 0           

8x + 0y = 16                                        3(2) - 2y = 0

8x = 16                                                 6 = 2y

x = 16/8 = 2                                         y = 6/2 = 3

QUESTION 2

4x + 3y = 7                           4x + 3y = 7                                                          y = 1

(x – 2y = -1) -4                     -4x + 8y = 4 +                                                     x – 2y = -1

                                               0x + 11y = 11                                                      x – 2(1) = -1

                                                       11y = 11                                                       x – 2 = -1

                                                           Y = 11/11 = 1                                         x = -1 + 2 = 1
